Question 305300
the second angle of a triangle is two times as large as the first. The third angle is 15 degress less than the sum of the other two angles.Find the measure of the first angle

let first angle be x
the second angle will be 2x

third angle = 2x+x -15 = 3x-15
.
x+2x+3x-15=180

6x=195

x= 32.5 degrees
